Exploring Cells and Their Structures

What are the main parts of a cell?

• Cell wall, chloroplasts, vacuoles

• Cell membrane, cytoplasm, nucleus, mitochondria, ribosomes, endoplasmic reticulum.

• Golgi apparatus, lysosomes, cytoskeleton

• Plasma, blood cells, tissues

Describe the function of the nucleus in a cell.

• The nucleus functions as the control center of the cell, containing DNA and regulating gene expression.

• The nucleus transports nutrients throughout the cell.

• The nucleus is responsible for protein synthesis.

• The nucleus produces energy for the cell.

What are two key differences between plant and animal cells?

• Animal cells have a cell wall; plant cells do not.

• Plant cells are smaller than animal cells.

• Animal cells contain chloroplasts; plant cells do not.

• 1. Plant cells have a cell wall; animal cells do not. 2. Plant cells contain chloroplasts; animal cells do not.

Explain the three main points of cell theory.

• All living organisms are made of tissues and organs.

• The three main points of cell theory are: 1) All living organisms are made of cells, 2) The cell is the basic unit of life, and 3) All cells come from existing cells.

• All cells are identical in structure and function.

• Cells can spontaneously generate from non-living matter.

Label the parts of a plant cell in a diagram.

• Cell Wall, Cell Membrane, Cytoplasm, Nucleus, Chloroplasts, Vacuole, Mitochondria

• Endoplasmic Reticulum

• Ribosome

• Cellulose

What is the function of the cell membrane?

• The cell membrane stores genetic information.

• The cell membrane is responsible for protein synthesis.

• The cell membrane regulates the movement of substances in and out of the cell.

• The cell membrane provides energy for cellular processes.

Compare prokaryotic cells to eukaryotic cells.

• Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.

• Eukaryotic cells lack a nucleus and are simpler than prokaryotic cells.

• Prokaryotic cells are larger and more complex than eukaryotic cells.

• Prokaryotic cells are simpler, smaller, and lack a nucleus; eukaryotic cells are larger, complex, and have a nucleus.

What role do ribosomes play in a cell?

• Ribosomes store genetic information in a cell.

• Ribosomes transport nutrients across the cell membrane.

• Ribosomes generate energy for cellular processes.

• Ribosomes synthesize proteins in a cell.

Identify one function of the chloroplast in plant cells.

• Photosynthesis

• Water storage

• Protein synthesis

• Cellular respiration

How does the shape of a cell relate to its function?

• Cell shape is determined solely by its size.

• Cell shape has no impact on function.

• All cells have the same shape regardless of function.

• The shape of a cell is adapted to its specific function, enhancing efficiency and effectiveness in its role.
